Details

Suited to transporting hot or cold liquids or gases. It’s with non-hygroscopic glass fiber or aerogel, complete with a heat reflective foil wrap and a weather-resistant outer jacket. It is supplied in long length coils(maximum 300m). Unlike field fabricated and insulated tube, it is pre-insulated and can be quickly and easily installed. It is less costly and effective and also guarantees semi permanent use and lasting warmth.
